Wingsteed Rider

The clean teaching version of heroic, and the card a generation of players learned the mechanic on. The 2/2 body is unremarkable on its own, and that is the point: every gain comes from spending other cards on it. Cast a pump spell, an Ordeal, a combat trick, or a protective spell like Gods Willing, and the +1/+1 counter is a free rider on a spell you wanted to cast anyway. The flying matters more than the body suggests, because a heroic engine that grows vertically is one your opponent's ground blockers cannot interact with; each counter widens the clock instead of just winning a stalled board. What heroic changes about the classic creature-plus-pump plan is not the sequencing problem (it makes it worse, since the creature has to hit the board before any spell can target it) but the payoff: the same trick that would have been a one-turn size bump now leaves a permanent counter behind, so investment compounds instead of evaporating at end of turn. The fragility is the counterweight. A two-power flier that needs enablers to matter draws a single removal spell mid-combat, and when it dies it takes your trick down with it and the whole snowball unwinds. That brittleness buys the growth, and it is the lesson the mechanic was designed to teach: the counters are permanent, but the creature carrying them is not.
